Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for controlling a projection device.
background
At present, cameras are installed on electronic equipment, particularly intelligent terminals such as smart phones and tablet computers. Generally, when an electronic device with a projection function is used, if the projection function is to be exited, a preset hardware button or a virtual keyboard is required to select the exit function. Therefore, the user can not use the projection device conveniently, for example, when projection is carried out and other functions need to be switched to immediately, the projection function is selected to be quitted, and then other functions are selected, so that the eyes of the user can be affected by light generated by projection to cause discomfort. Therefore, the projection function provided in the prior art may not provide more flexible use experience for the user due to the fact that various control operations cannot be provided.
in the prior art, document CN101889246A proposes a method of determining whether an object is placed in the field of view of a projector by detecting, by a detector, a change in the reflected beam of light of the projected beam of light reflected from the object, and turning off the output of the projector if the object is placed in said field of view. According to the scheme, whether the working state of the projector is closed or adjusted is judged by detecting whether an object is shielded in the view field, and automatic control of the projector is realized.
However, in practical applications, there are many types of obstructions, for example, a part of a human body, or other objects such as documents, and different obstructions often have different performance requirements on the detector, so that there is a possibility of misjudgment; in addition, the projector is also shielded unintentionally during use, and the method cannot judge whether shielding is intentional or unintentional, so that the possibility of misjudgment also exists; finally, as the use requirements of people are continuously improved, the projection area of the projector is continuously increased, and the detector faces the continuously increased projection area, so that the detection performance and the accuracy of the detector cannot meet the actual requirements easily.
Therefore, a method for automatically controlling a projector with higher recognition accuracy needs to be provided, so that a user can have good use experience in different use scenes.

Detailed Description
The embodiments of the present invention are further described below with reference to the drawings.
The first embodiment is as follows:
The invention provides a projection equipment control method, which comprises the following steps:
S1, the projector projects the light beam to the display device at a first angle, and the detector detects the reflected light beam of the projected light beam at a second angle, the second angle being different from the first angle;
S2, if the detector detects the reflected light beam, activating a thermal imaging device to detect heat of a obstruction causing the reflected light beam; returning to step S1 if the reflected beam is not detected by the detector;
S3, if the heat of the shielding object is larger than a preset heat threshold value and the shielding time of the shielding object is larger than a preset time threshold value, automatically converting the projector into a standby state or a power-off state; and if the heat of the shielding object is smaller than a preset heat threshold value or the shielding time of the shielding object is smaller than a preset time threshold value, maintaining the working state of the projector. Because the heat of a human body is often greater than that of a conventional article, and in an office scene, the walking of a person often means that a conference is ended and the projection equipment is used completely, the identification of the blocking object based on the heat is substantially to identify whether the blocking object is the human body and a certain part of the human body, while the blocking of the office article is usually unconscious blocking, and the blocking of the walking of the person is often the blocking after the conference is ended, so that the walking of the person can be approximately understood as conscious blocking; therefore, the shielding caused by the walking of the personnel is used as the basic basis for judging whether the projector is used or not, so that the situation that all shielding is used as the basis for judging whether the projector is used or not in the prior art is effectively avoided, and the accuracy of judgment is improved.
As a preferred embodiment, the step S3 further includes: if the heat of the shielding object is larger than a preset heat threshold value, detecting the shielding area of the shielding object in the projection view field of the projector, and if the ratio of the shielding area of the shielding object in the projection view field to the projection area is larger than a preset area ratio, automatically converting the projector into a standby state or a power-off state; and if the ratio of the shielding area of the shielding object in the projection field of view to the projection area is smaller than the preset area ratio, maintaining the working state of the projector. Because unconscious shielding is usually shielding with a small area, the shielding area ratio reflects whether the shielding is conscious from another angle, and the shielding caused by the walking of the personnel is used as the basis for basically judging whether the projector is used completely, thereby further improving the accuracy of judging whether the shielding object is conscious shielding.
as a preferred embodiment, the step S3 further includes: if the heat of the shielding object is larger than a preset heat threshold value, detecting the position of the shielding object in a projection visual field of the projector, and if the shielding object is at the upper part of the projection visual field, keeping the working state of the projector; and if the obstruction is at the lower part of the projection visual field, automatically converting the projector into a standby state or a power-off state. Similarly, because the unconscious shielding is usually the shielding at the lower half part of the projection view field, the shielding part reflects whether the shielding is conscious from another angle, and the shielding caused by the walking of the personnel is used as the basis for basically judging whether the projector is used completely, thereby further improving the accuracy of judging whether the shielding object is conscious shielding.
As a preferred embodiment, the step S3 further includes: if the heat of the shielding object is larger than a preset heat threshold value, the projector is automatically switched to a standby state, and if the user does not restart the projector within a preset time range, the projector is automatically turned off.
as a preferred embodiment, the step S3 further includes: if the heat of the shielding object is larger than a preset heat threshold value, detecting the moving speed of the shielding object in the projection field of view of the projector, and if the moving speed of the shielding object is larger than a preset speed threshold value, keeping the working state of the projector; and if the moving speed of the shielding object is less than a preset speed threshold value, automatically converting the projector into a standby state or a power-off state. Similarly, because unconscious shielding often has a faster moving speed in a projection view field, the moving speed of the shielding object reflects whether the shielding is conscious from another angle, and the shielding caused by the walking of people is used as a basic basis for judging whether the projector is used completely, so that the accuracy of judging whether the shielding is conscious is further improved.

in addition, the invention provides a control device of a projection device, which comprises the following modules:

The detection module is used for starting the thermal imaging equipment to detect the heat of the shielding object causing the reflected light beam when the detector detects the reflected light beam;
The state adjusting module is used for detecting the moving speed of the shielding object in the projection field of view of the projector when the heat of the shielding object is larger than a preset heat threshold value, and keeping the working state of the projector if the moving speed of the shielding object is larger than the preset speed threshold value; and if the moving speed of the shielding object is less than a preset speed threshold value, automatically converting the projector into a standby state or a power-off state. Because the heat of a human body is often greater than that of a conventional article, and in an office scene, the walking of a person often means that a conference is ended and the projection equipment is used completely, the identification of the blocking object based on the heat is substantially to identify whether the blocking object is the human body and a certain part of the human body, while the blocking of the office article is usually unconscious blocking, and the blocking of the walking of the person is often the blocking after the conference is ended, so that the walking of the person can be approximately understood as conscious blocking; therefore, the shielding caused by the walking of the personnel is used as the basic basis for judging whether the projector is used or not, so that the situation that all shielding is used as the basis for judging whether the projector is used or not in the prior art is effectively avoided, and the accuracy of judgment is improved. Similarly, because unconscious shielding often has a faster moving speed in a projection view field, the moving speed of the shielding object reflects whether the shielding is conscious from another angle, and the shielding caused by the walking of people is used as a basic basis for judging whether the projector is used completely, so that the accuracy of judging whether the shielding is conscious is further improved.
as a preferred embodiment, the state adjustment module further includes: if the heat of the shielding object is larger than a preset heat threshold value, detecting the shielding area of the shielding object in the projection view field of the projector, and if the ratio of the shielding area of the shielding object in the projection view field to the projection area is larger than a preset area ratio, automatically converting the projector into a standby state or a power-off state; and if the ratio of the shielding area of the shielding object in the projection field of view to the projection area is smaller than the preset area ratio, maintaining the working state of the projector. Because unconscious shielding is usually shielding with a small area, the shielding area ratio reflects whether the shielding is conscious from another angle, and the shielding caused by the walking of the personnel is used as the basis for basically judging whether the projector is used completely, thereby further improving the accuracy of judging whether the shielding object is conscious shielding.
As a preferred embodiment, the state adjustment module further includes: if the heat of the shielding object is larger than a preset heat threshold value, detecting the position of the shielding object in a projection visual field of the projector, and if the shielding object is at the upper part of the projection visual field, keeping the working state of the projector; and if the obstruction is at the lower part of the projection visual field, automatically converting the projector into a standby state or a power-off state. Similarly, because the unconscious shielding is usually the shielding at the lower half part of the projection view field, the shielding part reflects whether the shielding is conscious from another angle, and the shielding caused by the walking of the personnel is used as the basis for basically judging whether the projector is used completely, thereby further improving the accuracy of judging whether the shielding object is conscious shielding.
as a preferred embodiment, the state adjustment module further includes: if the heat of the shielding object is larger than a preset heat threshold value, the projector is automatically switched to a standby state, and if the user does not restart the projector within a preset time range, the projector is automatically turned off.
The invention provides a control method and a control device of a projection device, which are used for identifying whether shielding is unconscious shielding or not by judging the type of a shielding object, so that the control accuracy of a projector is improved; on the basis, various shielding object identification methods are provided, such as judging whether the shielding object is unconscious shielding based on the shielding area, judging whether the shielding object is unconscious shielding based on the position of the shielding object, judging whether the shielding object is unconscious shielding based on the moving speed of the shielding object, and the like, so that the accuracy of shielding object identification is improved, and the risk that the projection equipment is misjudged to influence the user experience due to unconscious shielding is reduced.
